The Christie administration is monitoring the Oyster Creak nuclear power plant that lost part of its power and declared an “alert” due to rising water levels Monday night.

Generators are powering the plant in New Jersey’s Lacey Township to keep the fuel cool. The nuclear facility lost a portion of its warning-alarm system Monday night, but other warning signals continued to function, Gov. Chris Christie said in statement Tuesday.

The Nuclear Regulatory Commission said that the plant remains in “safe condition” and federal and state inspectors are on site at the plant, which had been shut down before the storm.
